Gluteal Region

Description

Posterior surface anatomy of the coxal region is rendered on a muscular adult Black male, with the rounded contour dominated by the gluteus maximus and the inferior gluteal fold marking the transition to the posterior thigh. Superiorly, the pelvic silhouette is suggested by the iliac crests and the midline sacral region, with the intergluteal cleft orienting you to the median plane. Laterally, the buttock fullness tapers toward the greater trochanter region and the proximal iliotibial tract line along the lateral thigh, while the upper hamstring mass is apparent just inferior to the ischial region beneath the gluteal fold. Surface landmarks in this view guide safe injection technique and correlate with deep neurovascular anatomy. Locating the superolateral quadrant of the buttock relative to the iliac crest helps avoid the sciatic nerve and inferior gluteal vessels that course deep to gluteus maximus, a mistake still seen in poorly taught intramuscular gluteal injections. The posterior gluteal profile also supports teaching hip abductor mechanics, since weakness of gluteus medius and minimus (deep and lateral to gluteus maximus) drives a Trendelenburg gait and can be provoked in lateral hip pain syndromes, including greater trochanteric pain syndrome and gluteal tendinopathy. Rehabilitation teams and sports medicine educators can pair this posterior view with palpation labs to map the iliac crest, gluteal fold, and trochanteric region before discussing injection sites, posterolateral hip approaches, and common pain referral patterns. It also fits well in anatomy and surface anatomy modules for medical, nursing, and physiotherapy programs, or in patient-facing material where skin tone representation matters.
